Research highlighted: Ecology and Biotechnology of Selenium Respiring Bacteria

The American Society for Microbiology accepted a paper on the microbial conversion of selenium compounds for the March edition of Microbiology and Molecular Biology Reviews (MMBR). Piet Lens, Professor of Environmental Biotechnology and Venkata Yarlagadda, Senior Lecturer of the Marie Curie programme performed the research. It is the first time a UNESCO-IHE paper has been accepted in this journal.

Important advances in selenium bioreduction and its biotechnological applications in bioremediation, wastewater treatment and selenium recovery are presented in the March issue of Microbiology and Molecular Biology Reviews. The paper focuses on:

  • Presenting the ecology and microbiology of biological selenium cycle
  • Reviewing biochemistry of microbial reduction mechanisms of selenium oxyanions
  • Biotechnological application of selenium bioreduction in treatment of selenium wastewaters
  • The potential challenges in biological selenium recovery
  • The future directions in selenium bioreduction

The group of Prof. Piet Lens is considered a leading research team in the field of biological treatment of selenium wastewaters and selenium recovery using anaerobic granular sludge in UASB reactors.

The research on selenium bioremediation in terms pollution prevention and recovery of scarce and multi-faced element has wider implications in the public domain. For example, selenium ingestion at moderate concentrations is recommended in medical formulations and food supplements for anti-aging and reducing the risk of cancer.
